Are the means of da'wah (calling others to Islam) restricted to what is prescribed?

Question:
May Allah reward you. Honorable Shaykh, he says: Are the means of da'wah (calling others to Islam) based on specific textual evidence, or are they a matter of independent legal reasoning, or do they include both?

Answer:
The means are not based on specific textual evidence. The means, which involve using inventions such as radio broadcasts or audio tapes, are whatever Allah has made permissible, and they are means of good that are utilized for good. However, the methodologies of da'wah are based on specific textual evidence. The methodologies of da'wah are based on specific textual evidence, because we follow the methodology of the Messenger of Allah (peace and blessings be upon him) and the methodology of the righteous predecessors. So the methodologies of da'wah are based on specific textual evidence, and the methods of da'wah are based on specific textual evidence, because methods and methodologies mean the same thing. As for the means of da'wah by which the call is conveyed, there is nothing wrong with them. Now we have newspapers, magazines, and papers. We have radio. We have microphones. We have audio tapes. These were not present on earth before. These are merely means that have been made available for da'wah to do good work.
